Hi there. I've got a black polo 04 9n and I'm thinking of getting a K&N 57i induction kit for it. Not bothered with performance enhancement I just want a bit of a sporty sound I dont really like the engine noise from it at least on mine its sorta whistly. I want to know from any1 who has a 9n with one of these on was it easy to fit, and how it affects fuel consumption, cos mine is already terrible - if i drive no faster than 50mph on the main roads and gear change as early as possible I can expect 40mpg but normal driving is around 30.
I'm 17 and my insurance is £2800 with provident for TP only, but I might change to tescos cos i work there and can use my discount, lol, to get around £1600. Also I want to know if having the kit would seriously affect this price. The cars out of warranty.
Cheers, Dan
iv got a k&n sitting in the attic, i removed it as I found i was getting 15-20 miles less or so each time I went to fill up Same route to and from work as I used to before the filter. Could be just me though, i dont know
Sounds pretty good though. Easy to fit, straight forward.
i had 1 for my car and it snapped, i then got a 1.4 lupo sport 1 and that works fine same sound and simple to fit, but iv been told they lose about 3 bhp because they suck hot air in straight from the engine,didnt realy notice any change in the fuel to be honest
Thanks for all the feedback - I bought the kit today just need to get it up and running could anyone tell me how to remove the plastic engine cover as in my last mods i broke some things... not in the engine mind

You have to give it a firm tug(its a real snug fit)
Cheers so i don't need to disconnect or unscrew anything first other than the negative battery terminal. And will the cover fit back on once ive fitted it?

no, just pull it off u dont put the cover back on no, and u dont need to disconnect the negative battery terminal, dont know why it tels u 2 to be honest lol.
Right thanks Steve, it doesn't make sense to put it back on its just on the instruction sheet its got a man removing it with a k and n transfer on and I just thought what is the point in doing that if its to come off?

no idea at all lol, i put the k&n sticker on my battery cover
I'm wanting one of these too in the next week or so, are you serious you don't put the engine cover back on? Is that what you mean cos that sounds proper dodgey? Maybe thats put me off slightly!!!
Wey the filter thing looks as if it will sit on one of the rubber mounts that hold the airbox on. I'm gonna fit mine today ive had a bit fiddle but i can't unclip the breather hose from the side and I dont want to smash it. Is there a special way to unclip it? Cos the breather pipe just pulls off at the front. It's well stuck to the cam cover as well any tips on removing it without damage?
with regards to the complete box, you can just tug it off, and it will come off. You have 4 bungs that hold it on, one in each corner. Watch out for the rear RHS corner, you have 1 big breather pipe and 1 smaller vacuum pipe. Disconnet these from the air box by pulling them back towards the FRONT of the car. They will simply slide off.
I took my engine cover / air box off ages ago, coz it broke! I worked out why I kept on blowing coil packs.. The engine cover bouncing up and down unsecurely, constantly wacking the poor coil packs at the front! That's why i went through all 3 coil packs in 6 months!! Hmm.. at least i got new ones on now :p hehe
Same route to and from work as I used to before the filter. Could be just me though, i dont know 
u dont put the cover back on no, and u dont need to disconnect the negative battery terminal, dont know why it tels u 2 to be honest lol.
